摘要
试验于2011年在红兴隆农业科研所、291农场试验站、友谊农场试验站3个地点进行,在直播田中对ACERO、BAS-TION 2个甜菜品种的XBEET及CHECK种子进行播种,对其出苗情况进行了研究。试验结果表明:不同地点两品种出苗进程规律相似,3个地点2个品种XBEET处理平均比CHECK处理Dpt提前5天、发芽峰值提高29%、日平均发芽率增加15%、GI增加41%,保苗率平均增加15%。
The experiment studied the seeds of XBEET and CHECK of the sugar beet ACERO,BASTION which were planted in fields of Hong Xing Long agricultural research institute,291 and You Yi farm stations in 2011.The seedling emergence was counted at the same time.The result showed that the seedling emergence procedure of the two varieties in different places had similar regulation.Compared with that of CHECK,the Ddp of XBEET was advanced five days in three places and the germination peak was promoted 29%.Daily average germination percentage increased 15%.GI increased 41% and survival rate of seedlings increased 15%.
